Unfortunately, an unneeded mainboard specific `pmio.h` was created
when merging the AMD Parmer and Thatcher ports.
Rudolf used the header from a more generic location
southbridge/amd/agesa/hudson/hudson.h
doing the the ASUS F2A85-M port, but did not delete the `pmio.h`
now unused `pmio.h` header file.
So adapt AMD Parmer and Thatcher to use the Hudson one as done for
the ASUS F2A85-M and delete the now unused mainboard specific header
file `pmio.h` to avoid duplication.

Including the header file `cpu/amd/amdfam14.h` declaring the

The same change was done in the following commit for the

There is an optimization that can take place when hole
carving in ranges above 4GiB. If the range is the last
range then there is no need to carve UC holes out from
the larger WB range.
This optimization also has the same assumption of choosing
WB as the default MTRR type: the OS needs to properly
handle accessing realloacted MMIO resources with PAT so
that the MTRR type can be overidden.
Below are results using a combination of options. The
board this was tested on has 10 variable MTRRs at its
disposal. It has 4GiB of RAM.

Some ranges would use less variable MTRRs if an UC area
can be carved off the top of larger WB range. Implement this
approach by doing 3 passes over each region in the addres space:
1. UC default type. Cover non-UC and non-WB regions with respectie type.
Punch UC hole at upper end of larger WB regions with WB type.
2. UC default type. Cover non-UC regions with respective type.
3. WB default type. Cover non-WB regions with respective type.
The hole at upper end of a region uses the same min alignment of 64MiB.
Below are results using a combination of options. The board this was
tested on has 10 variable MTRRs at its disposal. It has 4GiB of RAM.

- memranges_next_entry() - get the next entry after the one provide
These functions will be used by a follow on patch to the MTRR code

Downstream payloads may need to take advantage of caching the
ROM for performance reasons. Add the ability to communicate the
variable range MTRR index to use to perform the caching enablement.
An example usage implementation would be to obtain the variable MTRR
index that covers the ROM from the coreboot tables. Then one would
disable caching and change the MTRR type from uncacheable to
write-protect and enable caching. The opposite sequence is required
to tearn down the caching.

The CONFIG_CACHE_ROM support in the MTRR code allocates an MTRR
specifically for setting up write-protect cachine of the ROM. It is
assumed that CONFIG_ROM_SIZE is the size of the ROM and the whole
area should be cached just under 4GiB. If enabled, the MTRR code
will allocate but not enable rom caching. It is up to the callers
of the MTRR code to explicitly enable (and disable afterwards) through
the use of 2 new functions:
- x86_mtrr_enable_rom_caching()
- x86_mtrr_disable_rom_caching()
Additionally, the CACHE_ROM option is exposed to the config menu so
that it is not just selected by the chipset or board. The reasoning
is that through a multitude of options CACHE_ROM may not be appropriate
for enabling.

It supports merging and deleting ranges as well as filling in

Certain MMIO resources can be set to a write-combining cacheable

The IORESOURCE_UMA_FB and IORESOURCE_IGNORE_MTRR attributes
on a resource provided hints to the MTRR algorithm. The
IORESOURCE_UMA_FB directed the MTRR algorithm to setup a uncacheable
space for the resource. The IORESOURCE_IGNORE_MTRR directed
the MTRR algorithm to ignore this resource as it was used reserving
RAM space.
Now that the optimizing MTRR algorithm is in place there isn't a need
for these flags. All IORESOURCE_IGNORE_MTRR users are handled by the
MTRR code merging resources of the same cacheable type. The users
of the IORESOURCE_UMA_FB will find that the default MTRR type
calculation means there isn't a need for this flag any more.

The old MTRR code had issues using too many variable
MTRRs depending on the physical address space layout dictated
by the device resources. This new implementation calculates
the default MTRR type by comparing the number of variable MTRRs
used for each type. This avoids the need for IORESOURE_UMA_FB
because in many of those situations setting the default type to WB
frees up the variable MTTRs to set that space to UC.
Additionally, it removes the need for IORESOURCE_IGNORE_MTRR
becuase the new mtrr uses the memrange library which does merging
of resources.
Lastly, the sandybridge gma has its speedup optimization removed
for the graphics memory by writing a pre-determined MTRR index.
That will be fixed in an upcoming patch once write-combining support
is added to the resources.
Slight differences from previous MTRR code:
- The number of reserved OS MTRRs is not a hard limit. It's now advisory
as PAT can be used by the OS to setup the regions to the caching
policy desired.
- The memory types are calculated once by the first CPU to run the code.
After that all other CPUs use that value.
- CONFIG_CACHE_ROM support was dropped. It will be added back in its own
change.
A pathological case that was previously fixed by changing vendor code
to adjust the IO hole location looked like the following:
MTRR: Physical address space:
0x0000000000000000 - 0x00000000000a0000 size 0x000a0000 type 6
0x00000000000a0000 - 0x00000000000c0000 size 0x00020000 type 0
0x00000000000c0000 - 0x00000000ad800000 size 0xad740000 type 6
0x00000000ad800000 - 0x00000000d0000000 size 0x22800000 type 0
0x00000000d0000000 - 0x00000000e0000000 size 0x10000000 type 1
0x00000000e0000000 - 0x0000000100000000 size 0x20000000 type 0
0x0000000100000000 - 0x000000014f600000 size 0x4f600000 type 6
As noted by the output below it's impossible to accomodate those
ranges even with 10 variable MTRRS. However, because the code
can select WB as the default MTRR type it can be done in 6 MTRRs:
MTRR: default type WB/UC MTRR counts: 6/14.
MTRR: WB selected as default type.
MTRR: 0 base 0x00000000ad800000 mask 0x0000007fff800000 type 0
MTRR: 1 base 0x00000000ae000000 mask 0x0000007ffe000000 type 0
MTRR: 2 base 0x00000000b0000000 mask 0x0000007ff0000000 type 0
MTRR: 3 base 0x00000000c0000000 mask 0x0000007ff0000000 type 0
MTRR: 4 base 0x00000000d0000000 mask 0x0000007ff0000000 type 1

If a configuration was not using RELOCTABLE_RAMSTAGE, but it
was using HAVE_ACPI_RESUME then the ACPI memory was not being
marked as reserved to the OS. The reason is that memory is marked as
reserved during write_coreboot_table(). These reservations were
being added to cbmem after the call to write_coreboot_table(). In
the non-dynamic cbmem case this sequence is fine because cbmem area
is a fixed size and is already reserved. For the dynamic cbmem case
that no longer holds by the nature of the dynamic cbmem.

The Broadcom BCM5785 GbE MAC integrated in the AMD Hudson-E1 requires a
secret sauce firmware blob to work. As Broadcom wasn't willing to send us
any documentation (or a firmware adapted to our Micrel PHY) I had to figure
out everything by myself in many weeks of hard detective work.
In the end we had to settle for a different solution, the modified firmware
I devised for the Micrel KSZ9021 PHY on our early FrontRunner-AF prototypes
is no longer needed for the production version. However the information
contained here might be very useful for others who'd like to use a
competing PHY instead of Broadcom's 50610, so it should not get lost.
And of course the unmodified, but now in large parts documented Selfboot
Patch is needed to get Ethernet on AMD Inagua. The code introduced here
should make the Hudson's internal MAC usable without having to add the
proprietary firmware blob. - At least in theory.
Unfortunately we've been unable to actually test this patch on Inagua,
therefore the broadcom_init() call in mainboard.c was left commented out.
If you have the hardware and can confirm it works please enable it.
The fun thing is: as Broadcom refused to do any business with us at all,
or send us any documentation, we never had to sign an NDA with them. This
leaves me free to publish everything I have found out. :-)

The ramstage is now linked using an intermediate object that
is created from the complete list of ramstage object files.
The rmodule code was developed when ramstage was linked using
an archive file. Because of the fact that the rmodule headers
are not referenced from any other object the link could start
by specifying the rmodule header object for ramstage. That,
however, is not the case as all ramstage objects are included
in the intermediate linked object. Therefore, the
ramstage_module_header.ramstage.o object file needs to be removed
from the object list for the ramstage rmodule.

The amd_mtrr.c file contains a copy of the fixed MTRR algorithm.
However, the AMD code needs to handle the RdMem and WrMem attribute
bits in the fixed MTRR MSRs. Instead of duplicating the code
with the one slight change introduce a Kconfig option,
X86_AMD_FIXED_MTRRS, which indicates that the RdMem and WrMem fields
need to be handled for writeback fixed MTRR ranges.
The order of how the AMD MTRR setup routine is maintained by providing
a x86_setup_fixed_mtrrs_no_enable() function which does not enable
the fixed MTRRs after setting them up. All Kconfig files which had a
Makefile that included amd/mtrr in the subdirs-y now have a default
X86_AMD_FIXED_MTRRS selection. There may be some overlap with the

The patch is based on Thatcher board. So far it boots Linux (3.2/3.7),
internal network adapter works, AHCI works. External PCI/PCIe slots
works too. Power management/ACPI seems to work.
Internal VGA works with dumped ROM (VGA/DVI), but lacks GART.
PCI pref devices are being relocated by Linux, reason unknown.
This is a good start.
USB and XHCI untested but visible.

The coreboot include were not being passed correctly when

This patch implements support for vboot firmware selection. The vboot
support is comprised of the following pieces:
1. vboot_loader.c - this file contains the entry point,
vboot_verify_firmware(), for romstage to call in order to perform
vboot selection. The loader sets up all the data for the wrapper
to use.
2. vboot_wrapper.c - this file contains the implementation calling the vboot
API. It calls VbInit() and VbSelectFirmware() with the data supplied
by the loader.
The vboot wrapper is compiled and linked as an rmodule and placed in
cbfs as 'fallback/vboot'. It's loaded into memory and relocated just
like the way ramstage would be. After being loaded the loader calls into
wrapper. When the wrapper sees that a given piece of firmware has been
selected it parses firmware component information for a predetermined
number of components.
Vboot result information is passed to downstream users by way of the
vboot_handoff structure. This structure lives in cbmem and contains
the shared data, selected firmware, VbInitParams, and parsed firwmare
components.
During ramstage there are only 2 changes:
1. Copy the shared vboot data from vboot_handoff to the chromeos acpi
table.
2. If a firmware selection was made in romstage the boot loader
component is used for the payload.
Noteable Information:
- no vboot path for S3.
- assumes that all RW firmware contains a book keeping header for the
components that comprise the signed firmware area.
- As sanity check there is a limit to the number of firmware components
contained in a signed firmware area. That's so that an errant value
doesn't cause the size calculation to erroneously read memory it
shouldn't.
- RO normal path isn't supported. It's assumed that firmware will always
load the verified RW on all boots but recovery.
- If vboot requests memory to be cleared it is assumed that the boot
loader will take care of that by looking at the out flags in
VbInitParams.
Built and booted. Noted firmware select worked on an image with
RW firmware support. Also checked that recovery mode worked as well
by choosing the RO path.

Convert the existing haswell code to support reloctable ramstage

this option is a hard requirement for relocatable ramstage.
Aside from converting a few new API calls, a cbmem_top()
implementation is added which is defined to be at the begining of the
TSEG region. Also, use the dynamic cbmem library for allocating a
stack in ram for romstage after CAR is torn down.
Utilizing dynamic cbmem does mean that the cmem field in the gnvs
chromeos acpi table is now 0. Also, the memconsole driver in the kernel
won't be able to find the memconsole because the cbmem structure
changed.

Here's the great news: From now on you don't have to worry about
hitting the right io.h include anymore. Just forget about romcc_io.h
and use io.h instead. This cleanup has a number of advantages, like
you don't have to guard device/ includes for SMM and pre RAM
anymore. This allows to get rid of a number of ifdefs and will
generally make the code more readable and understandable.
Potentially in the future some of the code in the io.h __PRE_RAM__
path should move to device.h or other device/ includes instead,
but that's another incremental change.

This patch fixes an issue for rmodules which are copied into memory
at the final load/link location. If the bss section is cleared for
that rmodule the relocation could not take place properly since the
relocation information was wiped by act of clearing the bss. The
reason is that the relocation information resides at the same
address as the bss section. Correct this issue by performing the
relocation before clearing the bss.

This patch adds a parallel implementation of cbmem that supports
dynamic sizing. The original implementation relied on reserving
a fixed-size block of memory for adding cbmem entries. In order to
allow for more flexibility for adding cbmem allocations the dynamic
cbmem infrastructure was developed as an alternative to the fixed block
approach. Also, the amount of memory to reserve for cbmem allocations
does not need to be known prior to the first allocation.
The dynamic cbmem code implements the same API as the existing cbmem
code except for cbmem_init() and cbmem_reinit(). The add and find
routines behave the same way. The dynamic cbmem infrastructure
uses a top down allocator that starts allocating from a board/chipset
defined function cbmem_top(). A root pointer lives just below
cbmem_top(). In turn that pointer points to the root block which
contains the entries for all the large alloctations. The corresponding
block for each large allocation falls just below the previous entry.
It should be noted that this implementation rounds all allocations
up to a 4096 byte granularity. Though a packing allocator could
be written for small allocations it was deemed OK to just fragment
the memory as there shouldn't be that many small allocations. The
result is less code with a tradeoff of some wasted memory.
+----------------------+ <- cbmem_top()
| +----| root pointer |
| | +----------------------+
| | | |--------+
| +--->| root block |-----+ |
| +----------------------+ | |
| | | | |
| | | | |
| | alloc N |<----+ |
| +----------------------+ |
| | | |
| | | |
\|/ | alloc N + 1 |<-------+
v +----------------------+
In addition to preserving the previous cbmem API, the dynamic
cbmem API allows for removing blocks from cbmem. This allows for
the boot process to allocate memory that can be discarded after
it's been used for performing more complex boot tasks in romstage.
In order to plumb this support in there were some issues to work
around regarding writing of coreboot tables. There were a few
assumptions to how cbmem was layed out which dictated some ifdef
guarding and other runtime checks so as not to incorrectly
tag the e820 and coreboot memory tables.
The example shown below is using dynamic cbmem infrastructure.
The reserved memory for cbmem is less than 512KiB.

This makes use of the new functions from pmutil.c that take
care of the differences between -H and -LP chipsets.
It also adds support for the LynxPoint-LP GPE0 register block
and the SMI/SCI routing differences.
The FADT is updated to report the new 256 byte GPE0 block on
wtm2/wtm2 boards which is too big for the 64bit X_GPE0 address
block so that part is zeroed to prevent IASL and the kernel
from complaining about a mismatch.
This was tested on WTM2. Unfortunately I am still unable to get an
SCI delivered from the EC but I suspect that is due to a magic
command needed to put the EC in ACPI mode. Instead I verified that
all of the power management and GPIO registers were set to expected
values.
I also tested transitions into S3 and S5 from both the kernel and
by pressing the power button at the developer mode screen and they
all function as expected.

The kernel ACPI was not happy with the Add inside a
ResourceTemplate (or perhaps within the IO declaration)
Instead make a buffer of IO reservations and turn _CRS
into a method that updates the buffer depending on the
chipset type.
This adds an \ISLP() method that checks the chipset LPC
device ID to see if it is -LP or -H.
It also increases the PM base reservation to 256 bytes
and moves both GPIO and PM base to above 0x1000 on -LP
chipsets.

This was put in for debugging and experimentation on i945
and has been copied around since. Drop it from lynxpoint.

There are subtle yet significant differences in some of the
registers in the power management region between LynxPoint-H
and LynxPoint-LP.
In order to reduce code that is accessing these registers and
would need special cases this adds a number of helper functions
that can be used in both ramstage and SMM.
This commit just adds the new functions, subsequent commits will
start to use them.

These base addresses are used in several places and it
is helpful to have one location that is reading it.

Add a helper function pch_is_lp() that will return 1 if
the current chipset is of the new "low power" variant used
with Haswell ULT.
Additionally these functions are added to SMM so it can
be used there.

I'm not sure if I screwed this up originally or the Intel docs changed
(I didn't bother to go back and check). According to ME BWG 1.1.0 the give
up bit is in the host general status #2 register.

The RESET_ON_INVALID_RAMSTAGE_CACHE option indicates what to do
when the ramstage cache is found to be invalid on a S3 wake. If
selected the system will perform a system reset on S3 wake when the
ramstage cache is invalid. Otherwise it will signal to load the
ramstage from cbfs.
